[Peterd] “I’m looking for a way to take some footage captured as standard 4:3 and simulate a anamophic squeeze on it. Basically I want ot do the opposite of setting the anamorphic setting in the item properties.
This problem has nothing to do with outputting to a 16:9 screen or anything. I was given footage for a project and some is anamoprhic and some is 4:3 letterboxed. I need all the footage to match on the final sequence in as unletterbox anamoprhic. Is there any way FCP can do this without sacrificing too much quality?”
Peter, its a damn weird request … to do what you seem to want to do, you would have to both distort (apect ratio: +33) and scale (133%) each clip, causing the top and bottom to be cropped and the remaining video to occupy the full 4:3 window (looking tall and thin), then export. on reimporting the footage, and applying the anamorphic flag, it will squish down and appear to be undistorted and 16:9.
But heres the thing, what you thing you want to do is not what you really should do. There is nothing to be gained by this except unnecessary loss of quality.
Do as advised above. Combine the 4:3 and anamorphic footage as is, in the anamophic timeline and scale the 4:3 clips to 133%, now you can reframe those clips as required and get on with the show.
Cheers
Andy
